摘要： A system for enhancing command scheduling is provided. In particular embodiments, the system includes a processor and a scheduler that receives commands from the processor for accessing a storage device. The scheduler receives a set of commands, some of which have a deadline, and the scheduler is configured to determine an execution order for those commands. The scheduler is also configured to defer the execution of one or more of those commands to a later time.

摘要： A system for enhancing the reliability of file systems is provided. In particular embodiments, the system includes a data storage device that includes one or more journal blocks, one or more primary metadata blocks, and one or more mirror metadata blocks. The system also includes a file system that writes metadata to the one or more journal blocks before writing the metadata to both the one or more primary metadata blocks and to the one or more mirror metadata blocks.

摘要： A system includes a storage device and a scheduler. The scheduler determines if deadlines of requests for accessing the storage device fall within first and second sliding windows. The scheduler issues requests that are in the first sliding window in a first order of execution and requests that are in the second sliding window in a second order of execution.
摘要翻译： 系统包括存储设备和调度器。 调度器确定访问存储设备的请求的最后期限是否落入第一和第二滑动窗口内。 调度器按照执行的第一顺序执行处于第一滑动窗口中的请求，并以第二次执行顺序发出处于第二滑动窗口中的请求。

摘要： Techniques for optimizing hard disk drive performance. According to one embodiment, a storage system includes a storage unit that stores data and a controller. The controller receives an idle mode indication and performs at least one operation based on the idle mode indication. According to another embodiment, a host system includes a processor and a scheduler that is operative to issues commands. The processor computes the idle mode indication, and the processor sends the idle mode indication to the storage system.
